EXPLOSION-MOTUR.

Specification of Letters Patent.

Patented Feb. e, 1912.

To all whom it may concern:

Be it known that I, PAULQDAHHER, a sub ject of the King of Wurttemberg,and resident of 87 Waiblingerstrasse, Cannstatt, in the Kingdom ofWurttemberg, Germany, have invented certain new and useful Improvementsin or Relating to Explosion- Motors, of which the following is aspecification.

'llhis invention relates to the particular arrangement of the sparkingdevice for explosion motors particularly intended foraeronauticalvehcles and'y also to the arrangement of the cold water pumpand oilpump. Y s

Hitherto it has beenusual to arrange the sparking device laterally ofthe motor, the driving spindle of the sparking device being arrangedparallel to the motor shaft. This arrangement has the disadvantage thatspecial drive is required for the sparln'ng device and that the surfaceexposed to the resistance of the air during the travel ofthe vehicle isincreased owing-to the sparking device projecting laterally from themotor.

lit has also hitherto been usual to arrange the water pump and oil pumpat the side of the motor casing and operate them each by special drive,the driving spindles of the pumps being also arranged parallelly to themotor shaft. `Such an arrangement 'possesses the same disadvantages asthat of the laterally arranged sparking device.

According to the present invention the hereinbefore mentioneddeficiencies are obviated by rranging thesparking device at one end ofhe motor with its driving spindle vertical an driven directly from themotor shaft through suitable bevel gear. The sparking device, water pumpand oil-pump are pre erably arranged one above another at one end of themot/or and mutually driven from the motor shaft, the water pump beingpreferably arranged in the middle with its driving spindle in alinernentwith the motor shaft and capable of being directly coupled therewith,while the spindles ofthe sparking device and oil pump are arrangedvertical and driven from the motor shaft through suitable bevel gear.VBy this arrangement the surface exposed to the resistance of the air isnot increased as there-is no projection beyond the side of the motor. n

ln order that the invention may be more Aclearly understood, referenceis made to the accompanying drawings, `which show byA way of example the.preferred method of carrying out the invention. Flgurel 's adetail sideView showing th location of the waterpump, lsparking device and oil pumprelativelyV to the motor, and Fig. 2'isa front view of the same.

Arranged in frontY of orbehind the'motor is the water pump b,- thedriving spindle cof which -is arranged in alinement with the motorshafta. s The sparking device d is arrangedabove the water-pump with itsdriving spindle f vertical, and below the water pump is located` the,oil pump or lubricating device g which is likewise arranged'with itsdriving spindle la. vertical. The oil` pump canof course be arrangedabove the Water pump and the sparking device below thesame. The spindlec of the water pump carries a bevel wheel z', which gears with gearwheels la and Z on the ends of the spindles f and h respectively, the

bevel wheel or spindle c being capable ofl being directly coupled withthe motor shaft a so that the water pump, sparking device and oil pumpcan be simultaneously driven from the motor shaft. The vertical spindlesof the-sparking device and oil-pump must of course be arranged inlbearings which take up radial and axial thrlists as indicated on thedrawings.

The apparatus as shown on the drawings has been. arranged in the middleof. the end surface of the motor casing, the longitudinal axis of themotor passing through the planeindicated' by the line A-B in Fig. 2.

The hereinbefore described arrangement has the advantage that owing. tothe absence of the hitherto usual indivldual drive for the-differentapparatus, the safe driving 0f the motor is insured, while owing to. theabsence of lateral brackets for the apparatus the weight of the motor isdecreased and owing to the arrangement of the apparatus at one end ofthe motor the surface exposed to the resistance of the air is decreasedas compared with the heretofore usual arrangement.

l. In combination with an explosion motor` a sparking device, a coolingwater pump and an oil pump, each arranged at one end of the motor andone above another, and

of the motor and one aboveV another, said water pump being arranged withits driving spindle in axial alinement with the Inotor shaft, and meanswhereby said sparking device water-pump and oil-pump may be mutuallyland directly driven from the mo- `arranged vertically, an means wherebysaid tor Shaft.

.S-In combination with an explosion motor,'"a sparking device, acooling4 water pump and an oil-pump, each arranged at one end ofthemotor and one above (another, said water pump being arranged with itsdriving spindle in axial alinementLwith the motor shaft, .andthe saidsparking device and oilpump and the driving s indles thereof beingsparking device, water-pump and oil-pump may be mutually and directlydriven from the motor shaft.

4. In combination with an explosion motor, va sparking device, a coolingwater pump and an oil-pump, each arranged at one end of the motor andone above another, said water pump beingv arranged with itsdrivingspindle in axial alinement with the motor shaft, and the saidsparking device and oil-pump and the driving spindles thereof beingarranged vertically, gearing intermediate the spindle of said water-pumpand the spindles of said oil-pump and sparking device and means forcoupling the spindle of the water pump with the motor shaft. i

In Witness whereof I have hereunto Set my hand in the presence of twowitnesses.A
